Typical tactics, always suspecting someone of being someone else. I think it's some type of psychological coping to force yourself to think there are fewer opponents of Feeneyism, and as if hardly anyone can think similarly. Apparently LoT and Nado must have given you a run for your money because you keep bringing those names up.
Trying to insult you? Believe me, if I wanted to insult you I wouldn't merely state your name! No, I wasn't trying to insult you; I am trying to make you more responsible in your carryings-on here.
The "Nadonian absurdity of "negative infallibility""? You are the one alone who made up that term! And you even have the notion that just because you haven't heard sedevacantists express themselves in such a manner that it means they don't believe it?? That is not even logical.
Lastly, I never said it is impossible that the Church could ever fail to condemn "any error whatsoever". Bad memory? or just dishonest?
It is not beneath you to go against past approved Catholic publications, but if you look up the infallibility of the believing Church, all Catholics surely believe it.
